The Looming Selection Dilemma at McDiarmid Park

Martin O'Neill finds himself walking a tightrope at Celtic as injury recoveries and international duties collide. Ahead of Wednesday evening's trip to face St Johnstone, the 74-year-old manager must weigh the return of key starters against the momentum of a squad grinding out domestic results.

Danish forward Kasper Hogh and Scotland left-back Kieran Tierney are both on the verge of returning to first-team action. Hogh, who arrived from Norwegian club Bodo/Glimt as Celtic's record signing this summer, has been sidelined since the Champions League play-off second leg against LASK on August 25.

Before his injury, the Denmark international hit the ground running with 3 goals in 5 games across all competitions. His physical presence inside the penalty box gave Celtic a direct aerial threat and an immediate focal point in attack.

Hogh trained with the squad on Monday and Tuesday, giving him an extra day of preparation compared to other returning teammates. O'Neill acknowledged that having the big striker back in training offers a major boost, but evaluating his match sharpness remains the final hurdle.

Meanwhile, Kieran Tierney missed recent league victories over Aberdeen and St Mirren with a minor muscle problem. The Scotland full-back joined the squad for light training on Tuesday morning as medical staff evaluated his readiness for match action.

Having Tierney back gives Celtic defensive stability along the left flank, where his recovery pace and overlapping runs add vertical balance. However, rushing either player into Wednesday's starting lineup carries genuine risk with a brutal schedule right around the corner.

With high-intensity derbies and European nights fast approaching, O'Neill cannot afford to trigger a relapse for either star. Pushing returning players too hard on Perth's tight pitch could turn a temporary injury concern into a long-term absence.

Camilo Duran's Explosion Creates a Good Problem

When Hogh limped off during the play-off defeat to LASK, Celtic faced an immediate goalscoring crisis. Summer signing Camilo Duran answered the call by stepping into the central striker role with devastating efficiency.

The Colombian forward has poured in 6 goals in 8 matches this season, transforming from a rotational option into Celtic's most dangerous attacking threat. His sharp movement in the box and relentless press gave opponents fits during Hogh's absence.

Duran was originally brought in to provide wide attacking depth, but his instinct inside the six-yard box forced O'Neill to re-evaluate his central options. Now, with Hogh returning, the veteran manager faces a complex selection puzzle.

As BBC Sport reported, O'Neill believes the solution comes down to flexibility rather than strict positional loyalty.

"it's a matter of trying to get your best players on the field"

Re-integrating Hogh could mean shifting Duran back out to a wider position where he started the campaign. However, moving Duran away from the central channel risks disrupting his rhythm right when he is scoring at will.

Celtic paid a record transfer fee for Hogh to anchor their attack as a natural number nine. Yet benching a red-hot striker like Duran would send the wrong signal to a squad that relied heavily on his goals over the past month.

Alternatively, O'Neill could alter his tactical shape to field both forward options simultaneously. That approach risks sacrificing a body in central midfield, creating defensive gaps that sharper opponents can exploit on the break.

Losing Yang Hyun-jun Before the Four-Game Gauntlet

While Hogh and Tierney near a return, Celtic must cope without winger Yang Hyun-jun. The 24-year-old South Korea international has departed to represent his country at the Asian Games, ruling him out for Celtic's next four matches.

Yang's departure comes at an brutal time for O'Neill. The winger's work rate off the ball has been essential to Celtic's high-pressing system, helping cover defensive gaps when full-backs push high up the pitch.

O'Neill did not hide his admiration for the wide man's recent performances during press conferences this week. The veteran manager praised Yang's output both in possession and out of it.

"He's playing exceptionally well for what he does with the ball... It's terrific, he's scored a couple of very important goals for us."

Losing Yang forces O'Neill to rethink his wide options across a grueling stretch of games. The South Korean will miss Wednesday's match at St Johnstone, Sunday's cup derby at Ibrox, the Europa League opener against Ferencvaros, and a second clash with Rangers.

Finding someone to match Yang's defensive tracking will be tough. If Celtic's wide substitutes fail to put in the dirty work, the defense could be left exposed against top European and domestic opposition.

Yang scored vital goals during Celtic's opening domestic run, demonstrating an ability to unlock compact low blocks. Replacing his creativity on the wing presents an immediate tactical challenge for a side facing packed defensive setups.

Why St Johnstone Matters More Than Ibrox Right Now

External attention in Glasgow is already drifting toward Sunday's Premier Sports Cup quarter-final against Rangers at Ibrox, scheduled for a 12:00 BST kickoff. Supporters and media outlets are eager to frame the derby as the ultimate test of Celtic's early-season credentials.

O'Neill, however, is refusing to bite. The Celtic boss insists that Wednesday's Premiership clash against St Johnstone is far more important than any cup fixture, no matter who the opponent is.

As confirmed in reports from BBC Sport, O'Neill is fully focused on securing three points on the road to protect Celtic's league standing.

"To me, this game is far more important than Sunday's match."

That perspective is classic O'Neill. League titles are built on cold Wednesday nights in Perth, not just flashy cup ties in Govan. Dropping points at McDiarmid Park would undermine all the momentum Celtic built in wins over Aberdeen and St Mirren.

St Johnstone will treat Celtic's visit as their own cup final, aiming to disrupt O'Neill's build-up play with physical tackling and aerial battles. If Celtic enter Perth with one eye on Sunday's trip to Ibrox, they risk getting caught flat-footed.

The 74-year-old manager knows that title defenses require total focus on immediate hurdles. A professional victory at St Johnstone sets the proper tone before entering the cauldron of an away derby.

European Disappointment and Squad Resilience

It is worth remembering that Celtic's season has not been a smooth march of victories. The failure to reach the Champions League main stage after losing to Austrian side LASK remains a painful black mark on the campaign.

That play-off defeat cost the club millions in European revenue and dropped Celtic into the Europa League. It also exposed structural weaknesses when key players are unavailable, proving that squad depth remains fragile under pressure.

O'Neill knows that winning domestic silver cannot completely erase European disappointment. But navigating this four-match gauntlet without Yang while managing Hogh's return will show whether this squad has truly learned from the LASK collapse.

The upcoming Europa League opener against Hungarian champions Ferencvaros will test Celtic's European credentials once again. Returning to winning ways on the continent requires a stable domestic foundation built during matches like St Johnstone.

If Duran continues his scoring streak and Tierney restores balance to the backline, Celtic can solidify their domestic baseline before European group fixtures begin. If O'Neill gets his tactical selection wrong on Wednesday, the pressure ahead of Sunday's derby will turn suffocating.
